Lithium battery expert

Are you in doubt about the health of your battery? We offer you a precise battery diagnosis! We can test your battery life with a full report on the health of your battery.

This diagnostic allows you to know exactly how your battery is performing and whether an intervention is possible to restore it to its original performance. We can then offer you a rebalancing of the cells, a repair or a complete reconditioning.

Do you want to resell your battery or your bike, scooter…?

The comprehensive test report provided by OZO helps reassure your buyer about the condition of the battery.

When a battery less than 3 years old fails, we offer a repair service.

Current repair:

- Power take-off

- Charging

- Neiman

- BMS (Battery Management System)

- Carter

- fuse

- Fairing

- Barrel

 Advanced repair :

- Nickel electrofusion allowing the cells to be bonded.

- Balancing in voltage and cell capacity allowing to recover between 20% and 50% of additional autonomy.

If the battery is over 3 years old and you experience a loss of power or range, no longer charging, or your charger remains green, it often needs to be reconditioned. We recover your battery, then we dismantle and recycle your old cells while keeping your original casing.

2 choices are then available to you:

- Identical replacement: you regain your original autonomy while having a weight gain thanks to the use of high-end cells from Samsung or Panasonic in 3500mAh.

- Increase the capacity: The use of 3500mAh cells makes it possible to increase the energy volume of the cell pack and therefore to be able to integrate a larger capacity in the same volume to gain autonomy.

As part of an identical exchange of batteries, you keep your original charger.

Is your original battery lead?

We can offer you a lithium retrofit: The battery will be 4 to 5 times lighter, for an equivalent autonomy and you can also increase your autonomy for the same volume. If you switch to Lithium, your original lead charger will no longer be compatible and you will need to purchase a Lithium charger.

Repair and reconditioning are two processes that extend the life of your battery and are carried out in our battery laboratory, located in Éguilles near Aix-en-Provence.

These 100% French solutions reduce the carbon footprint by half compared to buying a new lithium battery while being more economical for the end user.

Reconditioning and repairing Lithium batteries are the most ecological solutions.

OZO contributes to an approved organization for the recycling of used batteries that cannot be repaired.

Lithium batteries contain substances that can pose a risk to the environment if discarded in nature. Proper sorting and treatment allows them to be recycled and to avoid any pollution. Almost 77% of the materials present in lithium batteries can thus be reused during the manufacture of new objects to replace natural resources. 

The diagnostic case is an easy-to-use tool that fits in your pocket and allows you to diagnose a fault in 5 minutes on electrically assisted bicycles or other electric mobility devices.

With this suitcase you will be able to test the following elements:

- Engine hall sensor
- Motor phases
- Pedal sensor
- Controller
- Accelerator
- Brake cut-off

Second essential tool for the proper functioning of your workshop, The battery test bench.

It allows to test the residual capacity of any battery between 12V and 72V, whether it is an electric bicycle battery, electric scooter, golf cart, electric scooter, electric boat ...

The discharge current is adjustable from 1A to 15A and it is possible to define discharge stages to best represent the actual conditions of use.

At the end of the discharge test, you can print a detailed report showing all the test parameters and the discharge curve.

You understand, the OZO battery test bench will allow you to offer a new service to your customers but also to improve the profitability of your workshop.
